The short answer is results will vary….but a long time! Because of all of the different situations out there, we do not guarantee a time period. The 25oz bottles hold ice cold for approximately 18 hours. Some tell us about how they left their Thinksport bottle in the car in 100-degree weather only to return to clinking ice five hours later. Others tell us how we kept their drinks cold for longer than 24 hours. One customer even puts our bottle in a thermal testing chamber and reported that it was the best bottle he had ever seen. On average the sports bottles hold contents hot for 4 hours. Because of the double-walled construction, you also won't feel the temperature of the products. So it is important to be careful if you've placed hot liquids into the bottle.

Do your bottles fit in cup holders or water bottle cages?

Thinksport 350ml/12oz and 500ml/17oz bottles are designed to fit in car cup holders while our 750ml/25oz bottles fit some (but not all). 12oz and 500ml bottles will fit into water bottles cages. The 750ml fits most bottle cages on spin bikes.
